不同隔板汽封的泄漏特性比较

Comparison of Leakage Characteristics of Steam Seal with Different Separator

以某中小型汽轮机的两种隔板汽封系统为研究对象,通过对其汽封流场进行数值模拟,比较了多种工况下不同汽封的泄漏性能和结构特点,分析了这两组汽封的优缺点,为中小型隔板汽封的优化设计提供了参考。

With a small steam turbine two diaphragm gland seal system as the research object, through the numerical simula-tion of the steam seal flow field, different steam seal leakage performance and structural characteristics are compared under va-rious conditions, the advantages and disadvantages of the two sets of steam seal are analyzed, which provide reference for opti-mization design of small and medium clapboard steam seal.
